GREASE GUN FILLER Filed Feb. 25, 1937 2 Sheets-Sheet 2 Patented May 3, 1938 N UNITED' STATES PATENT OFFICE 6 ClaimsL i This invention relates to apparatus for use in filling grease guns with lubricant.

As is well known to those skilled in the art, lubricating grease is sold usually in cans. An object of the present nvention is to provide simple, efficient and compact means whereby the contents of a can, can be discharged therefromv at will and in controllable quantities for the purpose of filling a grease gun or the like when necessary.

With the foregoing and other objects in View which will appear as the description` proceeds, the inventlo n consists of certain novel details of Construction and combinations of parts hereinafter more fully described and pointed out in the claims, it being understood that changes may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed. i 20 In the accompanying drawings the preferred forms of the invention have been shown.

In said drawings:

Figure 1 is a side elevation of the apparatus showing -a lubricant containing can` in position therein ready for delivery of its contents.

Figure 2 is a front elevation.

Figure 3 is a top plan View.

Figure 4: is an enlarged section on line 4-4, Figure l.

Figure 5 is a section on line 5-5, Figure 4.

Figure 6 is a side elevation of the apparatus showing the parts positioned during the application of the filled can thereto.

Figur-e 7 isa section through a slightly modified form of head which can be used with the apparatus.

Referring to the figures by characters of reference l designates a tubular socket having diverging legs 2 and 3 for supporting it in a substantiallyvertical position. This socket is provided with one o-r more set screws 4 or similar tdevicesfor the purpose of fastening the lower end of a 'standard 5 within' the socket.

Adjustably mounted on the standard 5 near one end is a sleeve 6 having a set screw 'I or the like whereby the sleeve can be held in any position to which it may be moved along the standard. This sleeve is located at the outer end of an arm 8 which is made integral with a head 9 the diameter of which is somewhat greater than that of the bottom of the can C to be used in the apparatus. The bottom of the head can be provided with a gasket lo of cork or any other suitable material adapted to fit snugly against the bottom of the can C and, if desired, a circular recess H can be formed in the bottom of the head to receive the bead c usually iormed around the bottom of a can. Thus it will be seen that head 9 can be caused to fit snugly against the bottom'o-f an inverted can as shown particularly in Figure 4. i

Extending'through the head 9 at the center thereof is an'opening 12 the upper end of which is normally closed by a screw plug I 3 or other removablewand tight fitting closure. A by-pass l4 extends within` the head from this opening to a nozzle !5 located beyond the head and supported thereby. The outletgend of this nozzle can be closed normally by a cap !6.

In the structureshown Lin Figure 4 the nozzle is made up of tubular members detachably connected to one side of thehead but it is to be understood that, if desired, the by-pass, as shown at ll in Figure 7, can be extended within a downwardly turned arm |8 integral with the head andinto' which the depending ,nozzle l9 is inserted. i\

Mounted ontthe standard 5 near that end remote from` the sleeve. E is another sleeve 20 which can be held inany desired position on the standard by means of'a set screw 2l or the like. An arm. or bracket 22 is extended from this sleeve and has a bore 23 within which is slidably mounted a screw 24 engaged by an adjusting wheel 25. This wheel bears against the bracket 22.

screw 24 is alined with the opening !2 in head 9 and that end nearest the head is preferably angular in contour, as shown at 26 and seated within superposed disks 21 and 28 which are clamped upon a cup-like' disk 29 of rubber or other suitable material the marginal portion of which is extended toward head 9 and is adapted to frictionally engage the inner surface of a can C when placed in the apparatus. The disks 21 and 28 are held in firm contact with the interposed disk 29 by a nut 30 engaging a threaded stud 3! projecting from the end of screw 24 Mounted on the standard 5 between the sleeves 6 and`20 is a split sleeve 32 having spaced arms 33 extending-from the ends thereof and joining them to opposed edge portions of a band 34. This band is so proportioned as to fit snugly around the container C and, when the arms 33 are drawn toward each other by means of a tiebolt 35, the band will clamp tightly on the inserted can and hold it against radial expansion in Figure 1 and inverted so that the end which was formerly uppermost, can thus be inserted downwardly into the socket I and fastened, as shown in Figure 6. Thus head 9 will be brought to position below the follower formed by disks 21, 28 and 29. The can C containing the grease to be dispensed, is placed with its open end uppermost on the inverted head 9 and within the reenforcing band 34. The bailgenerally supplied with the can for use as a handle, is removed from the opposed sockets d usually provided on the can and the laterally turned upper ends 36 of tie-rods 31 are inserted into these sockets. screw threaded, are inserted through ears 38 at the margin of the head 9. By means of nuts 39 engaging these threaded ends, the rods are drawn tightly so as to bind the bottom of the can against the head.

After the can has thus been placed in position the follower made up of the disks 21, 28 and 29, is lowered into the open end of the can so that the marginal portion of disk 29 will hug closely tothe inner surface of the wall of the can. The follower is held in this position by adjusting the wheel 25 against the bracket 22. Band 34 is tightened about the can so as to hold it against expansion under pressure from within and standard 5 is then removed from socket I, 'reversed, and its other end inserted intothe socket so that the parts will thus be positioned as shown in Figures 1, 2 and 3.

The operator next removes the plug or other closure I 3 and, by means of any suitable tool inserted downwardly through the opening l2, punctures the bottom of the inverted can C. The plug or closure l3 is then replaced and the apparatus is ready for use.

When it is desired to withdraw a portion of the contents of the can, the cap |6 is removed and the grease gun or the like is attached to the nozzle [5. The follower is then ed upwardly toward the head 9 and within the can and will cause a portion of the grease to be expelled through opening l2 and by-pass l4 to nozzle |5 and thence to the grease gun.

Importance is attached to the provision of the reenforcing band 34 which serves to prevent the can from bursting while being subjected to pressure.

What is claimed is:

l. A grease dispenser including a base. an invertible standard detachably mounted at either end in the base, an apertured member thereon, a delivery nozzle carried by said member and communicating with the aperture, a iollower, means on the standard for adjustably supporting the follower for movement toward said member, and means on the standard for surrounding and gripping a grease container with its bottom against the apertured member and its open end positioned to receive the follower.

3. A grease dispenser including a base, an invertible standard detachably mounted at either end in the base, a member thereon having an aperture for the reception of a puncturing tool, a removable closure for the aperture, a delivery nozzle carried by said member and communicating with the aperture, means for holding a container with its bottom thrust against said member in position to be perforated by a tool inserted into the aperture, means on the standard for surrounding and gripping the container, a follower, and means on the standard for supporting the follower in position for insertion into the open end of the container.
